Due to previous failure of SSD drive from Goodram I was forced to use brand new 1TB HDD from Toshiba. It was not a problem because the system running on it mainly have been using writes with not too much reads. My SSD drive had some performance drops which could be because of the fact being run out of the same power socket shared with some DIY tools in garage. Now there is no power socket sharing I think that I may close server lid with too much force, so even brand new HDD failed. Proxmox reported failure of disk
If you want to run some curl on icon click from Ubuntu 22 panel, then you need to create file in ~/.local/share/applications: Then after few seconds, press special key (aka Windows key) and type your “application” name. You can grab and paste it onto application panel to be shown as a shortcut.
If you happen to have MacBookPro3,1 with Intel Core 2 Duo 2.2Hz DDR2 SDRAM with MacOS 10.8.5 on board then you probably wonder if there is a chance to access internet with modern browser. Yes, now you can with chromium downloader for chromium-legacy. https://github.com/blueboxd/chromium-legacy https://github.com/blueboxd/chromium-legacy/discussions/25 However there are reported some issues with NVIDIA GeForce 8600M GT 128MB GPU and I can confirm it also. If you download the latest, as for now 121, Chromium will be installed but no visible window content could be seen. Instead I downloaded stable 114 version which run just fine. Probably you could run more
In order to separate Proxmox node from cluster:
If you would like to run virtual machine inside another virtual machine, then you need to have CPU with nested virtualization feature and this feature needs to be enabled. Even if enabled: you might still have error on enabling virtualization inside virtual machine: Still, even with “KVM hardware virtualization” set to Yes on VM Options pane in Proxmox UI, you may have trouble to get it to work. In case of Intel Xeon Gold 5412U there are no additional CPU flags available to set from Proxmox UI. You need to select CPU type as “host” either from UI or inside
If you would like to control some electrical devices by switching them on and off then one possiblity is to use Rasberry Pi relay hat. It is from Waveshare/Botland and it fits on top of your Raspberry Pi. It contains 3 relays controllers with screw connectors. Once you wire your devices you can even put it within DIN box like this one below. Be sure to be careful inserting micro SD card as this box fits tight and you can easily break card apart like I once did. In order to control relay connectors first you export pins: Then you
Installing Redash is straightforward if you use https://github.com/getredash/setup repository. Just run setup script to download, install and configure all required packages. But there is one thing missing from the default. It is mail configuration. First install Redash with all default settings and then edit /opt/redash/env file: After setting those values run docker-compose up -d command to recreate containers. Use TLS and local IP address if you host your mail server on-premise. Now you should be able to send mail messages from your Redash.
Benefit from running your own docker registry is cost and privacy. But in order to use it in various places you need to secure its connection with SSL/TLS certificates. In case you have only ZeroSSL or LE certificates it can be difficult to maintain both you certificate at ACME/HAProxy leve in pfSense and secondary also in docker registry somewhere else. Fortunately there is solution for that. Add your docker registry domain to ACME certificate enrollment as usual. Run docker registry without giving it certificate. Instead configure a domain pointing at pfSense, preferably using non-WAN address. Next configure proxy-pass at Nginx
In case you have some LXC containers on your Proxmox server, then there is high chance that you will get some errors during backup them up. Some container templates may not support snapshot or suspend modes. Instead you should you use stop mode. It is important to remember that during such backup container will be stopped, so be aware of that in case you have some encryption which could ask for a key during startup.
